Webdesigner: Usage of standard icons

Hi together,

In the webdesigner, the standard icons e.g. used by the module VI_Menue_Line have "URL" as source.

For example the big user icon "User_48.png" is not available in a library but its called via a link.

So, to get the picture displayed you have to know the correct filename.

My question now is:

Is there a way to see which icons exist in the standard, as they are not findable for me.

I would need an icon like the "User_Plus_48.png" image but instead of a "Plus" symbol i would need a symbol like a check mark - does something like this exist?

Thanks in advance,
